Advance Information*

Stainless Steel Flat Bars: Comprehensive Product Description

Stainless steel flat bars are among the most fundamental yet versatile components in construction, fabrication, and manufacturing industries. Made from high-quality stainless steel, these bars are designed to meet rigorous industry standards while offering superior durability and performance. Stainless steel flat bars are particularly notable for their resistance to corrosion and oxidation, making them an ideal choice for applications exposed to various environmental elements.

Materials and Grades

Stainless steel flat bars are available in multiple grades, each offering unique properties suitable for different applications:

1. SS Grade 202:
2. An austenitic chromium-nickel-manganese stainless steel.
3. It offers a unique combination of strength, hardness, and workability.

4. A more cost-effective and durable alternative to traditional austenitic stainless steels.

5. SS Grade 304:

6. One of the most widely used stainless steels due to its excellent corrosion resistance.
7. It contains a higher level of chromium, making it more resistant to oxidation.

8. Ideal for applications requiring welding and heavy forming.

9. SS Grade 316:

10. Superior corrosion resistance compared to 304.
11. Contains molybdenum, which increases its resistance to chlorides and other industrial solvents.
12. Often used in marine environments, chemical processing, and medical applications.

Specifications and Dimensions

Stainless steel flat bars commonly come in a variety of sizes to meet different needs:

• Widths: Typically range from 20mm to 200mm.
• Thicknesses: Usually range from 3mm to 30mm.
• Lengths: Typically available in standard lengths, such as 6 meters, but can be custom-cut to specific requirements.

The dimensions and tolerances of the flat bars conform to international standards, ensuring high quality and consistency across batches.

Manufacturing Process

The production of stainless steel flat bars involves several critical steps to ensure product quality and performance:

1. Melting and Casting:
2. Raw stainless steel materials are melted in an electric arc furnace.

3. The molten steel is then cast into the desired shape, forming slabs.

4. Hot Rolling:

5. The slabs are heated and passed through rollers to achieve a flat, uniform thickness.

6. This process improves the mechanical properties and surface quality of the bars.

7. Cutting and Grinding:

8. The rolled bars are cut to standard or custom lengths.

9. Any surface imperfections are removed through grinding, producing a smooth and polished finish.

10. Heat Treatment:

11. Heat treatment processes like annealing may be applied to improve machinability and corrosion resistance.

12. Inspection and Quality Control:

13. Each flat bar undergoes rigorous inspections to ensure compliance with industry standards.
14. Various tests, such as tensile tests and ultrasonic inspections, are conducted to verify mechanical properties and structural integrity.

Key Features and Benefits

Corrosion Resistance

One of the standout features of stainless steel flat bars is their exceptional resistance to corrosion. This characteristic makes them suitable for outdoor applications and environments where exposure to moisture and chemicals is a concern. SS Grade 316, in particular, offers unparalleled resistance to chlorides and solutions used in industrial settings.
